Emma Wills & Probate Lawyer, Illinois

To deliberately prevent someone from inheriting something. This is usually done by a provision in a will stating that someone who would ordinarily inherit property -- a close family member, for example -- should not receive it. In most states, you cannot completely disinherit your spouse; a surviving spouse has the right to claim a portion (usually one-third to one-half) of the deceased spouse's estate. With a few exceptions, however, you can expressly disinherit children.

A complete listing of all property owned by a deceased person at the time of death. The inventory is filed with the court during probate. The executor or administrator of the estate is responsible for making and filing the inventory.

A document in which you specify what is to be done with your property when you die and name your executor. You can also use your will to name a guardian for your young children.

For federal estate tax filing purposes, the total of all property owned at death, without regard to any debts or liens against the property or the costs of probate. Taxes are due only on the value of the property the person actually owned (the net estate) plus the amount of any taxable gifts made during life. In a few states, the gross estate is used when computing attorney fees for probating estates; the lawyer gets a percentage of the gross estate.

In trademark law, a mark that is not inherently distinctive becomes protected after developing a 'secondary meaning': great public recognition through long use and exposure in the marketplace. For example, though first names are not generally considered inherently distinctive, Ben & Jerry's Ice Cream has become so well known that it is now entitled to maximum trademark protection.

A trust designed to save on estate tax. The trust principal is preserved for the trust maker's grandchildren, with his or her children receiving only income from the trust. Because the children (the middle generation) never legally own the property, it isn't subject to estate tax at their death. See generation-skipping transfer tax.

A federal tax imposed on money placed in a generation-skipping trust. Currently, there is a $1 million exemption to the GSTT; that is, each person may leave $1 million in a generation-skipping trust free of this tax. The GSST is imposed when the middle-generation beneficiaries die and the property is transferred to the third-generation beneficiaries. Every dollar over $1 million is subject to the highest existing estate tax rate--currently 55%--at the time the GSTT tax is applied.
